The game will hit the shelves on August 1st in Europe and August 24th in US. This was said about the various game modes:
”It is very simple… You put your hands on each side of the PS Vita, and with two fingers, one finger on the right side of the rear touch pad and another one on the left part of the rear touch pad, you press/touch each side to tilt the world, on the right or on the left.”
“It is the same way as the “normal” touch screen! (Front).” But we worked on this special aspect of the Vita because we thought the fingers on the front screen could hide the different dangers in the game. With this special feature, we can play the game (I do it by myself and I can assume it is one of the best way to control the game) without hiding anything on screen.”
Additionally, the game’s PS Vita edition will come with another 49 levels and gyroscopic motion controls.
